Nissan X-Trail 32. Instruction — part 1623

PB-18

< SYSTEM DESCRIPTION >

SYSTEM

• The parking brake automatically releases when vehicle is driven under the following conditions.
- Engine running.
- The selector lever is in the D or R position. (CVT models)
- The accelerator pedal is depressed.
- When engine torque necessary for travelling is generated after shifting the selector lever to other than P

range and N range, depressing the accelerator pedal and seat belt (driver side) is fastened. (CVT models)

- When engine torque necessary for travelling is generated after engaging the clutch and depressing the

accelerator pedal. (M/T models)

• When release of the parking brake is completed (not rotating torque generated by the motor in the parking

brake actuator), the electric parking brake indicator lamp turns OFF.

• When parking brake switch is pulled while driving, parking brake starts to operate (the motor in the parking

brake actuator starts generating rotating torque), and electric parking brake indicator lamp illuminates. When
pulling operation is stopped, the parking brake operation is canceled and electric parking brake indicator
lamp turns OFF.

• When parking brake is pulled while driving immediately before the vehicle stops, the parking brake begins to

be applied (the motor in the parking brake actuator starts generating rotating torque) and the electric parking
brake indicator lamp turns ON.
NOTE:
The parking brake braking force is weaker than when the vehicle is stopped until the vehicle comes to a
stop.

• When parking brake switch is pulled after vehicle stop, parking brake starts to operate again (tension is

loaded to rear cable), and electric parking brake indicator lamp turns OFF.

• When the parking brake braking force reaches the prescribed value (rotating torque generated by the motor

in the parking brake actuator), the electric parking brake indicator lamp turns ON.

• When the parking brake switch is pulled while travelling, a command is transmitted to the ABS actuator and

electric unit (control unit), and it applies brake on four wheels to reduce vehicle speed.
NOTE:
• When releasing the parking brake switch, the brake applied by the ABS actuator and electric unit (control

unit) is released.

• During the brake operation (deceleration) by the ABS actuator and electric unit (control unit), the status

becomes as follows:

- electric parking brake indicator lamp and master warning lam are turns ON.
- Buzzer is ON.
- “Release parking brake” is shown on the information display of the combination meter.
- Stop lamp is turn ON.
- If the parking brake switch is still pulled even after the vehicle speed becomes 4 km/h (2.5 MPH), the brake

operation (deceleration) by the ABS actuator and electric unit (control unit) is stopped, and the vehicle
speed is reduced by the braking force of parking brake.

CONDITION FOR TURN ON THE WARNING LAMP, THE INDICATOR LAMP AND INFORMATION
DISPLAY

Turns ON when ignition switch turns ON and turns OFF when the system is normal, for bulb check purposes.
